                     FORWARD-LOOKING STATEMENTS

This report on Form 10-Q contains forward-looking statements about Westamerica
Bancorporation for which it claims the protection of the safe harbor
provisions contained in the Private Securities Litigation Reform Act of 1995.
These forward-looking statements are based on Management's current knowledge
and belief and include information concerning the Company's possible or
assumed future financial condition and results of operations. A number of
factors, some of which are beyond the Company's ability to predict or control,
could cause future results to differ materially from those contemplated. These
factors include but are not limited to (1) a slowdown in the national and
California economies; (2) fluctuations in asset prices including, but not
limited to, stocks, bonds, real estate, and commodities; (3) economic
uncertainty created by terrorist threats and attacks on the United States, the
actions taken in response, and the uncertain effect of these events on the
national and regional economies; (4) changes in the interest rate environment;
(5) changes in the regulatory environment; (6) significantly increasing
competitive pressure in the banking industry; (7) operational risks including
data processing system failures or fraud; (8) the effect of acquisitions and
integration of acquired businesses; (9) volatility of rate sensitive deposits
and investments; (10) asset/liability management risks and liquidity risks;
(11) changes in liquidity levels in capital markets; and (12) changes in the
securities markets. The reader is directed to the Company's annual report on
Form 10-K for the year ended December 31, 2007, for further discussion of
factors which could affect the Company's business and cause actual results to
differ materially from those expressed in any forward-looking statement made
in this report. The Company undertakes no obligation to update any
forward-looking statements in this report.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Basis of Presentation

The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial information and pursuant to the rules and regulations of the
Securities and Exchange Commission. The results of operations reflect interim
adjustments, all of which are of a normal recurring nature and which, in the
opinion of Management, are necessary for a fair presentation of the results
for the interim periods presented. The interim results for the six months
ended June 30, 2008 and 2007 are not necessarily indicative of the results
expected for the full year. These unaudited consolidated financial statements
should be read in conjunction with the audited consolidated financial
statements and accompanying notes as well as other information included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2007.

Note 2: Significant Accounting Policies.

Certain accounting policies underlying the preparation of these financial
statements require Management to make estimates and judgments. These estimates
and judgments may affect reported amounts of assets and liabilities, revenues
and expenses, and disclosures of contingent assets and liabilities. The most
significant of these involve the Allowance for Credit Losses, which is
discussed in Note 1 to the audited consolidated financial statements included
in the Company's Annual Report on Form 10-K for the year ended December 31,
2007.

On January 1, 2008, the Company adopted the following new accounting
pronouncements:
- FASB Statement No. 157 ("FAS 157") - Fair Value Measurements
- FASB Statement No. 159 ("FAS 159") - The Fair Value Option for Financial
Assets and Financial Liabilities -- Including an Amendment of FASB Statement
No. 115

The adoption of FAS 157 and FAS 159 did not have any affect on the Company's
financial statements at the date of adoption.  For additional information, see
Note 3.

Recently Issued Accounting Pronouncements

In December 2007, the FASB issued FASB Statement No. 141 (revised 2007),
Business Combinations. This Statement replaces FASB Statement No. 141,
Business Combinations. This Statement retains the fundamental requirements in
Statement 141 that the acquisition method of accounting (which Statement 141
called the purchase method) be used for all business combinations and for an
acquirer to be identified for each business combination. This Statement also
retains the guidance in Statement 141 for identifying and recognizing
intangible assets separately from goodwill. This Statement requires an
acquirer to recognize the assets acquired, the liabilities assumed, and any
noncontrolling interest in the acquiree at the acquisition date, measured at
their fair values as of that date, with limited exceptions specified in the
Statement. That replaces Statement 141's cost-allocation process, which
required the cost of an acquisition to be allocated to the individual assets
acquired and liabilities assumed based on their estimated fair values.
Statement 141 required the acquirer to include the costs incurred to effect
the acquisition (acquisition-related costs) in the cost of the acquisition
that was allocated to the assets acquired and the liabilities assumed. This
Statement requires those costs to be recognized separately from the
acquisition. In addition, in accordance with Statement 141, restructuring
costs that the acquirer expected but was not obligated to incur were
recognized as if they were a liability assumed at the acquisition date. This
Statement requires the acquirer to recognize those costs separately from the
business combination. This Statement applies prospectively to business
combinations for which the acquisition date is on or after the beginning of
the first annual reporting period beginning on or after December 15, 2008. The
impact of this Statement on the Company's financial statements will be
contingent on the terms and conditions of future business combinations.


Page 8

In March 2008, the FASB issued FASB Statement No. 161, Disclosures about
Derivative Instruments and Hedging Activities-an amendment of FASB Statement
No. 133 ("FAS 161").  FAS 161 changes disclosure requirements for derivative
instruments and hedging activities.  The Statement requires enhanced
disclosures about (a) how and why derivative instruments are used, (b) how
derivative and related hedged items are accounted for under Statement 133 and
its related interpretations, and (c) how derivative instruments and related
hedged items affect financial position, financial performance, and cash flows.
This Statement is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2008, with early adoption
permitted.  The Company had no derivative instruments designated as hedges as
of June 30, 2008.  The Company will adopt FAS 161 on January 1, 2009.


Note 3:  Fair Values of Assets and Liabilities.

On January 1, 2008, the Company adopted the provisions of FAS 159, The Fair
Value Option for Financial Assets and Financial Liabilities -- Including an
Amendment of FASB Statement No. 115.  In accordance with FAS 159, the Company,
at its option, can value assets and liabilities at fair value on an
instrument-by-instrument basis with changes in fair value recorded in
earnings. The Company elected not to value any additional assets or
liabilities at fair value in accordance with FAS 159.

On January 1, 2008, the Company also adopted the provisions of FAS 157, Fair
Value Measurements, with the exception of the requirements that pertain to
nonfinancial assets and nonfinancial liabilities covered by FASB Staff
Position (FSP) No. FAS 157-2. FAS 157 defines fair value, establishes a
consistent framework for measuring fair value and expands disclosure
requirements for fair value measurements. FSP FAS 157-2 delays the effective
date of the FAS 157 requirements for nonfinancial assets and nonfinancial
liabilities to fiscal years beginning after November 15, 2008. Other real
estate owned is an example of a nonfinancial asset that the Company will be
required to measure at fair value on a non-recurring basis in accordance with
generally accepted accounting principles.

Fair Value Hierarchy

In accordance with FAS 157 the Company groups its assets and liabilities
measured at fair value in three levels, based on the markets in which the
assets and liabilities are traded and the reliability of the assumptions used
to determine fair value. These levels are:

* Level 1 - Valuation is based upon quoted prices for identical instruments
traded in active exchange markets, such as the New York Stock Exchange.  Level
1 also includes U.S. Treasury and federal agency securities, which are traded
by dealers or brokers in active markets. Valuations are obtained from readily
available pricing sources for market transactions involving identical assets
or liabilities.

* Level 2 - Valuation is based upon quoted prices for similar instruments in
active markets, quoted prices for identical or similar instruments in markets
that are not active, and model-based valuation techniques for which all
significant assumptions are observable in the market. Level 2 securities
include mortgage-backed securities, municipal bonds and collateralized
mortgage obligations.

* Level 3 - Valuation is generated from model-based techniques that use
significant assumptions not observable in the market. These unobservable
assumptions reflect the Company's estimates of assumptions that market
participants would use in pricing the asset or liability. Valuation techniques
include use of option pricing models, discounted cash flow models and similar
techniques.

The table below presents the balances of available for sale securities
measured at fair value on a recurring basis. (in thousands)

The Company does not record loans at fair value with the exception of impaired
loans which are measured for impairment in accordance with SFAS 114,
Accounting by Creditors for Impairment of a Loan, ("SFAS 114"). Under SFAS
114, loans measured for impairment based on the fair value of collateral or
observable market prices are within the scope of SFAS 157. Loans measured at
fair value on a non-recurring basis were measured for impairment by valuing
the underlying collateral based on third-party appraisals which are level 3
fair value measurements. At June 30, 2008, impaired loans totaled $8.3
million.

Note 6: Goodwill and Other Intangible Assets

The Company has recorded goodwill and other identifiable intangibles
associated with purchase business combinations. Goodwill is not amortized, but
is periodically evaluated for impairment. The Company did not recognize
impairment during the six months ended June 30, 2008 and June 30, 2007.
Identifiable intangibles are amortized to their estimated residual values over
their expected useful lives. Such lives and residual values are also
periodically reassessed to determine if any amortization period adjustments
are indicated. During the second quarter of 2008 and second quarter of 2007,
no such adjustments were recorded.

The changes in the carrying value of goodwill were ($ in thousands):

Note 7: Post Retirement Benefits

The Company offers a continuation of group insurance coverage to qualifying
employees electing early retirement, for the period from the date of
retirement until age 65. For eligible employees the Company pays a portion of
these early retirees' insurance premiums. The Company reimburses a portion of
Medicare Part B premiums for all qualifying retirees over age 65 and their
qualified spouses. Eligibility for post-retirement medical benefits is based
on age and years of service, and restricted to employees hired prior to
February 1, 2006. The Company uses an actuarial-based accrual method of
accounting for post-retirement benefits.

The following table sets forth the net periodic post-retirement benefit costs

The Company does not fund plan assets for any post-retirement benefit plans.

Note 8: Contingent Liabilities

In accordance with Visa's by-laws, the Company and other Visa U.S.A. member
banks are obligated to share in Visa's litigation obligations which existed at
the time of Visa's restructuring transactions. Accordingly, in the fourth
quarter 2007, the Company recorded estimated litigation liabilities and
related litigation expense related to Visa Inc. in the amount of $2,338
thousand. During the first quarter 2008, in accordance with the determination
of Visa Inc.'s Litigation Committee, Visa Inc. funded its litigation escrow
account with $3 billion of net proceeds from the Visa Inc. initial public
offering. This escrow account will be used to make payments related to certain
covered Visa litigation. At the time of escrow funding, the Company reduced
its litigation liability with a corresponding reversal of litigation expense
of $2,338 thousand representing the Company's portion of the escrow account
limited by the amount previously recognized as an expense.

We issue standby letters of credit, which include performance and financial
guarantees, for customers in connection with contracts between the customers
and third parties. Standby letters of credit commit the Company to make
payments on behalf of customers when certain specified future events occur.
Standby letters of credit are primarily issued to support customers'
short-term financing requirements and must meet the Company's normal credit
policies and collateral requirements. Standby letters of credit outstanding
totaled $32.0 million and $33.0 million at June 30, 2008 and December 31,
2007, respectively. We also had commitments for commercial and similar letters
of credit of $68 thousand and $613 thousand at June 30, 2008 and December 31,
2007, respectively.

Note 9: Earnings Per Common Share

The table below shows earnings per common share and diluted earnings per
common share. Basic earnings per share are computed by dividing net income by
the average number of shares outstanding during the period. Diluted earnings
per share are computed by dividing net income by the average number of shares
outstanding during the period plus the impact of common stock equivalents.

For the three months and six months ended June 30, 2008, all options
outstanding were included in the computation of diluted net income per share
because the fair value of the stock exceeded the option exercise price.
However, for the three months and six months ended June 30, 2007, options to
purchase 901 thousand and 911 thousand shares of common stock, respectively,
were not included in the computation of diluted net income per share because
the option exercise price exceeded the fair value of the stock such that their
inclusion would have had an anti-dilutive effect.

Item 2. Management's Discussion and Analysis of Financial Condition and
Results of Operations

Westamerica Bancorporation and subsidiaries (the "Company") reported second
quarter 2008 net income of $12.2 million or $0.42 diluted earnings per share.
These results compare to net income of $22.4 million or $0.74 diluted earnings
per share for the same period of 2007. In the second quarter of 2008, the
Company recognized a $10.5 million after-tax or $0.35 diluted earnings per
share securities impairment of Federal Home Loan Mortgage Corporation
("FHLMC") and Federal National Mortgage Association ("FNMA") preferred stock
held in its available for sale investment portfolio.

On a year-to-date basis, the Company reported net income for the six months
ended June 30, 2008 of $39.0 million or $1.33 diluted earnings per share,
compared with $45.9 million or $1.50 diluted earnings per share for the same
period of 2007. The first half of 2008 included the $10.5 million after-tax
impairment in the value of FHLMC and FNMA preferred stock and $4.7 million in
after-tax benefits from Visa's initial public offering which combined to
reduce net income by $5.8 million and earnings per diluted share by $0.20. The
first half of 2007 included $822 thousand in tax-exempt company owned life
insurance proceeds, representing $0.02 diluted earnings per share.

Following is a summary of the components of net income for the periods indicated
(dollars in thousands except per share data):

Net income for the second quarter of 2008 was $10.1 million less than the same
quarter of 2007, reflecting a $10.5 million after-tax FHLMC and FNMA preferred
stock impairment charge in the second quarter of 2008. Net interest income
(FTE) increased $3.7 million or 8.0%, the net result of lower funding costs,
partially offset by lower average earning assets and declining yields on
loans. The provision for loan losses increased $525 thousand, reflecting
Management's assessment of credit risk and the level of the allowance for loan
losses. Noninterest income fell $18.5 million primarily due to the above
impairment charge. Noninterest expense increased $1.6 million or 6.6% mostly
due to higher personnel and data processing costs. The provision for income
taxes (FTE) decreased $6.9 million mostly due to the $7.7 million tax benefit
of the impairment charge.

Comparing the first six months of 2008 to the prior year, net income decreased
$6.9 million or 15.1%, due to a charge for the impairment of FHLMC and FNMA
preferred stock and higher loan loss provision, partially offset by higher net
interest income (FTE), a gain on sale of VISA common stock and lower tax
provision (FTE). The higher net interest income (FTE) was mainly caused by
lower funding costs, partially offset by a lower volume of average
interest-earning assets and lower yields on loans. The provision for loan
losses increased $1.1 million to reflect Management's assessment of credit
risk and the level of the allowance for loan losses. Noninterest income
declined $14.4 million mainly due to the above impairment charge on FHLMC and
FNMA preferred stock, partially offset by the above gain on sale of VISA
common stock. Noninterest expense increased $23 thousand, primarily the net
result of higher data processing costs, partly offset by the reversal of a
$2.3 million accrual for Visa related litigation. The income tax provision
(FTE) decreased $3.8 million or 13.9% largely due to the above tax benefit
from the impairment charge, partially offset by an increase related to the
gain on sale of Visa common stock.

Net Interest Income

The Company's primary source of revenue is net interest income, or the
difference between interest income earned on loans and investments and
interest expense paid on interest-bearing deposits and borrowings. Following
is a summary of the components of net interest income for the periods
indicated (dollars in thousands):

                                                    ====================================================

    Average earning assets                            $3,865,110   $4,245,342   $3,946,665   $4,266,357

    Net interest margin (FTE)                               5.16%        4.36%        4.97%        4.38%



The Company's net interest margin has expanded during the three and six months
ended June 30, 2008 compared to the respective periods in 2007. The Federal
Reserve's Open Market Committee (FOMC) reduced the target federal funds rate
from 5.25 percent in August 2007 to 2.00 percent in April 2008 in seven
increments. As a result, short-term interest rates declined and the Company
managed to reduce the interest rates paid on deposits and other
interest-bearing liabilities during 2008 compared to respective periods in
2007. During this period, the Company's loan and investment yields were less
sensitive to changes in interest rates resulting in a lesser reduction in such
yields compared to the rates paid on deposits and other funding sources.
Offsetting some of the benefit of the expanding margin was the reduction in
the level of average interest-earning assets in 2008 relative to 2007.

Net interest income (FTE) rose during the second quarter of 2008 by $3.7
million or 8.0% from the same period in 2007 to $49.7 million, mainly due to
lower rates on average interest- bearing liabilities (down 126 basis points
("bp")) and lower average balances of those liabilities (down $336 million),
partly offset by lower average earning assets (down $380 million) and lower
yields on loans (down 35 bp).

Comparing the first six months of 2008 with the same period of 2007, net
interest income (FTE) increased $4.7 million or 5.1%, primarily due to lower
rates paid on interest-bearing liabilities (down 93 bp) and a lower average
volume of those liabilities (down $263 million), partially offset by lower
average earning assets (down $320 million) and lower yields on loans (down 26
bp).


Interest and Fee Income

Interest and fee income (FTE) for the second quarter of 2008 decreased $6.8
million or 10.4% from the same period in 2007. The decline was caused by lower
average balances of earning assets (down $380 million) and lower yields on
loans (down 35 bp).

In Management's opinion, current economic conditions are not conducive for
generating profitable loan growth. Recent downward pressure on real estate
values create a cautious view toward real estate lending, and economic
pressure on consumers has reduced demand for automobile and other consumer
loans. Additionally, yields available on the highest quality investment
securities do not offer an adequate profit margin over the cost of funding. As
a result, the Company has not taken an aggressive posture relative to current
loan and investment portfolio growth.

The decrease in the average earning assets in the second quarter of 2008
compared with the same period in 2007 was substantially attributable to a $303
million decline in the average investment portfolio: U.S. government sponsored
entity obligations (down $146 million), mortgage backed securities and
collateralized mortgage obligations (down $109 million), municipal securities
(down $40 million) and corporate and other securities (down $11 million).
Average total loans were lower by $77 million in the second quarter of 2008
compared with the same period in 2007 primarily due to decreases in the
average balances of commercial real estate loans (down $40 million),
residential real estate loans (down $27 million) and tax-exempt commercial
loans (down $15 million), partially offset by increases in the average
balances of consumer loans (up $7 million) and construction loans (up $6
million).

The average yield on the Company's earning assets decreased from 6.12% in the
second quarter of 2007 to 6.03% in the same period in 2008. The composite
yield on loans fell 35 bp to 6.34% due to decreases in yields on taxable
commercial loans (down 133 bp), real estate construction loans (down 450 bp),
consumer loans (down 29 bp) and commercial real estate loans (down 3 bp),
partially offset by higher yields on tax-exempt commercial loans (up 19 bp)
and residential real estate loans (up 9 bp). Real estate construction loans
and commercial lines of credit have variable interest rates based on the prime
lending rate. The prime lending rate averaged 8.25 percent in the second
quarter 2007 compared to 5.08 percent in the second quarter 2008, reducing the
yields earned on real estate construction loans and commercial lines of
credit. Additionally, a $10.3 million construction loan relationship was
placed on nonaccrual status during the second quarter with $203 thousand in
accrued interest reversed from interest income, which further reduced the
yield earned on construction loans during the period. Conversely, a commercial


Page 15

loan on nonaccrual status as of March 31, 2008 was returned to accrual status
upon receipt of all past due loan payments including $160 thousand in interest
recorded as interest income, which increased the yield on commercial loans
during the period. For more information regarding nonaccrual loans and
interest income recorded thereon, see the section entitled Nonperforming Loans
and Other Real Estate Owned. The investment portfolio yield increased 20 bp to
5.51%, mainly due to higher yields on mortgage backed securities and
collateralized mortgage obligations (up 7 bp), municipal securities (up 5 bp)
and U.S. government sponsored entity obligations (up 3 bp), partially offset
by corporate and other securities (down 17 bp). As investment portfolio
volumes have declined over the past year, municipal security volumes have
declined at a slower rate than the remainder of the investment portfolio. As a
result, municipal securities represented 51 percent of total average
investment security volumes during the second quarter 2008, compared to 44
percent during the second quarter 2007. This migration in the composition of
the investment portfolio has improved the overall yield of the investment
portfolio since municipal security yields exceed the yield of the overall
investment portfolio.

Comparing the first half of 2008 with the corresponding period a year ago,
interest and fee income (FTE) was down $11.0 million or 8.4%. The decrease
largely resulted from lower average balances of earning assets and lower
yields on loans.

Average earning assets decreased $320 million or 7.5% for the first half of
2008 compared with the same period of 2007, due to a $260 million decline in
the investment portfolio and a $60 million decrease in the loan portfolio.
Lower average investment balances were largely attributable to mortgage backed
securities and collateralized mortgage obligations (down $110 million), U.S.
government sponsored obligations (down $107 million), municipal securities
(down $37 million) and corporate and other securities (down $10 million). The
loan portfolio decline was primarily due to decreases in the average balances
of commercial real estate loans (down $45 million), residential real estate
loans (down $26 million), tax-exempt commercial loans (down $16 million) and
taxable commercial loans (down $6 million), partly offset by increases in the
average balance of consumer loans (up $20 million) and real estate
construction loans (up $14 million).

The average yield on earning assets for the first half of 2008 was 6.05%
compared with 6.12% in the corresponding period of 2007. The loan portfolio
yield for the first half of 2008 compared with the same period of 2007 was
lower by 26 bp, primarily due to decreases in yields on taxable commercial
loans (down 113 bp), construction loans (down 293 bp), consumer loans (down 17
bp) and commercial real estate loans (down 7 bp), partially offset by
commercial tax-exempt loans (up 9 bp) and residential real estate loans (up 8
bp). The investment portfolio yield rose by 12 bp. The increase resulted
mostly from higher yields on mortgage backed securities and collateralized
mortgage obligations (up 8 bp), partially offset by U.S. government sponsored
obligations (down 3 bp) and corporate and other securities (down 42 bp).


Interest Expense

Interest expense in the second quarter of 2008 decreased $10.4 million
compared with the same period in 2007. The decrease was attributable to lower
rates paid on the interest- bearing liabilities and lower average balances of
those liabilities.

The average rate paid on interest-bearing liabilities decreased from 2.56% in
the second quarter of 2007 to 1.30% in the same quarter of 2008. Rates paid on
most interest-bearing liabilities moved with general market conditions. Rates
on deposits decreased 74 bp to 1.07% primarily due to decreases in rates paid
on CDs over $100 thousand (down 262 bp), preferred money market savings (down
111 bp), retail CDs (down 49 bp) and money market checking accounts (down 11
bp). Rates on short-term borrowings also decreased 266 bp mostly due to lower
rates on federal funds purchased (down 313 bp) and line of credit and
repurchase facilities (down 252 bp).

Interest-bearing liabilities declined $336 million or 11.5% for the second
quarter of 2008 over the same period of 2007. Most categories of deposits
declined including money market savings (down $73 million), money market
checking accounts (down $30 million), regular savings (down $22 million) and
retail CDs (down $19 million). The decline was partially offset by a $34
million increase in preferred money market savings. Short-term borrowings
declined $222 million primarily due to a $210 million decrease in federal
funds purchased.

Comparing the first half of 2008 to the corresponding period of 2007, interest
expense decreased $15.7 million, due to lower rates paid on interest-bearing
liabilities and a decline in such liabilities.

Rates paid on liabilities averaged 1.58% during the first six months of 2008
compared to 2.51% in the first six months of 2007. The average rate on
short-term borrowings fell 209 bp to 2.29%, mainly due to declines on rates
paid on federal funds purchased (down 250 bp) and line of credit and
repurchase facilities (down 148 bp). Rates on deposits were also lower (down
50 bp). CDs over $100 thousand declined 205 bp and retail CDs decreased by 22
bp. Preferred money market savings decreased 79 bp.

Interest-bearing liabilities declined $263 million or 8.9% over the first half
of 2007 mainly due to decreases in the average balances of federal funds
purchased (down $121 million), money market savings (down $86 million), money
market checking accounts (down $35 million), regular savings (down $28
million), retail CDs (down $20 million) and line of credit and repurchase
facilities (down $16 million).

In all periods, the Company has focused its sales efforts on building the
balances of more profitable, noninterest bearing and lower-cost transaction
accounts in order to minimize the cost of funds.

During the second quarter of 2008, the net interest margin (FTE) increased 80
bp compared with the same period in 2007. Rates paid on interest-bearing
liabilities declined faster than yields on earning assets (FTE), resulting in
a 117 bp increase in net interest spread. The increase in the net interest
spread was partially reduced by the lower net interest margin contribution of
noninterest bearing funding sources. The margin contribution of noninterest
bearing funds decreased 37 bp because of the lower market rates of interest at
which they could be invested.

Similarly, the net interest margin (FTE) in the first six months of 2008 rose
by 59 bp when compared with the corresponding period of 2007. Earning asset
yields decreased 7 bp while the cost of interest-bearing liabilities declined
by 93 bp, resulting in an 86 bp increase in the net interest spread. The 27 bp
decrease in noninterest bearing funding sources lowered the increase in the
net interest margin.

Summary of Average Balances, Yields/Rates and Interest Differential

The following tables present, for the periods indicated, information regarding
the Company's consolidated average assets, liabilities and shareholders'
equity, the amount of interest income from average earning assets and the
resulting yields, and the amount of interest expense paid on interest-bearing
liabilities. Average loan balances include nonperforming loans. Interest
income includes proceeds from loans on nonaccrual status only to the extent
cash payments have been received and applied as interest income. Yields on
securities and certain loans have been adjusted upward to reflect the effect
of income which is exempt from federal income taxation at the current
statutory tax rate (FTE) (dollars in thousands).

    (1) Interest and rates calculated on a fully taxable equivalent basis using
    the current statutory federal tax rate.
    (2) Net interest spread represents the average yield earned on earning assets
    minus the average rate paid on interest-bearing liabilities.
    (3) Net interest margin is computed by calculating the difference between
    interest income and expense (annualized), divided by the average balance of
    earning assets.

    (1) Interest and rates calculated on a fully taxable equivalent basis using
    the current statutory federal tax rate.
    (2) Net interest spread represents the average yield earned on earning assets
    minus the average rate paid on interest-bearing liabilities.
    (3) Net interest margin is computed by calculating the difference between
    interest income and expense (annualized), divided by the average balance of
    earning assets.

Provision for Credit Losses

The Company manages credit costs by consistently enforcing conservative
underwriting and administration procedures and aggressively pursuing
collection efforts with troubled debtors. The Company provided $600 thousand
for loan losses in the second quarter of 2008, compared with $75 thousand in
the second quarter of 2007. For the first six months of 2008 and 2007, $1.2
million and $150 thousand were provided in each respective period. The
provision reflects management's assessment of credit risk in the loan
portfolio for each of the periods presented. For further information regarding
net credit losses and the allowance for credit losses, see the "Classified
Assets" section of this report.

Noninterest income for the second quarter of 2008 decreased by $18.5 million
from the same period in 2007 mainly due to the $18.2 million writedown of
FHLMC and FNMA preferred stock. During the second quarter of 2008, the Company
began issuing its own cashier's checks rather than use a vendor which paid the
Company fees based on the availability of funds while the cashier's checks
remained outstanding ("float"). By issuing its own cashier's checks, the
Company uses the related float as a source of funding and reduces its interest
expense. Such vendor fees were $279 thousand lower in the second quarter of
2008 compared with the same period of 2007. Service charges on deposit
accounts declined $187 thousand or 2.4% primarily due to decreases in
overdraft fees, returned item charges and service charges on retail and
business checking accounts (down $109 thousand).

In the first half of 2008, noninterest income decreased $14.4 million compared
with the same period of the previous year. Noninterest income for the 2008
period included the $18.2 million impairment charge and $5.7 million in
securities gains from the redemption of Visa Class B common stock as part of
Visa's initial public offering. Noninterest income for the six months of 2007
included an $822 thousand gain on company-owned insurance. Official check
issuance income declined $500 thousand because the Company began issuing its
own cashier's checks rather than use an outside vendor as mentioned above.
Service charges on deposit accounts decreased $419 thousand or 2.7% mainly due
to declines in overdraft fees, returned item charges and retail and business
checking account service fees (down $206 thousand). Financial services
commissions fell $169 thousand or 25.1%. Other noninterest income decreased
$321 thousand or 13.1% primarily due to a $260 thousand decline in interest
recoveries on charged-off loans.

Noninterest expense rose by $1.6 million or 6.6% in the second quarter of 2008
compared with the same period in 2007. Data processing service costs were $562
thousand or 36.4% higher due to conversion of the Company's item processing
function to an outside vendor in the third quarter of 2007. Salaries and
related benefits increased $443 thousand or 3.5%, mainly due to annual merit
increases granted to continuing staff and increases in payroll taxes, stock
based compensation and workers compensation. Professional fees increased $274
thousand mostly due to higher legal fees. Occupancy costs increased $101
thousand or 3.0%. Other noninterest expense rose by $468 thousand or 25.7%
largely due to increases in insurance costs and amortization of low-income
housing investments as tax benefits are realized. The above increases were
partially reduced by decreases in equipment expense (down $146 thousand or
12.7%) and amortization of intangible assets (down $105 thousand or 11.8%).

In the first six months of 2008, noninterest expense increased $23 thousand
compared with the corresponding period of 2007. The first six months of 2008
included a reversal of the $2.3 million accrual for Visa related litigation,
which was reversed with the funding of a litigation escrow as a part of the
Visa IPO. Data processing service costs were higher by $1.2 million or 37.8%
due to conversion of the Company's item processing function to an outside
vendor. Salaries and related benefits increased $860 thousand or 3.4% mainly
due to annual merit increases granted to continuing staff and increases in
payroll taxes, workers compensation and company match for the 401(k) plan.
Professional fees increased $315 thousand or 34.8% primarily due to higher
legal fees, partially offset by lower audit fees. Occupancy costs increased
$200 thousand or 3.0%. Other noninterest expense rose by $579 thousand or
16.4% due to higher insurance costs and amortization of low-income housing
investments as tax benefits are realized. Other categories of expense
decreased from the first six months of 2007, offsetting the increases outlined
above. Equipment expense declined $362 thousand or 15.8% mostly due to reduced
depreciation costs. Amortization of intangible assets decreased $222 thousand
or 11.9%. Correspondent service charges were lower by $125 thousand or 28.1%.


Provision for Income Tax

During the second quarter of 2008, the Company recorded income tax provision
(FTE) of $6.7 million compared with $13.6 million for the second quarter of
2007. The current quarter provision represents an effective tax rate of 35.6%,
compared to 37.9% for the second quarter of 2007 largely as a result of the
$7.7 million tax benefit of the impairment charge and higher tax credits from
low-income housing investments.

On a year-to-date basis, the income tax provision (FTE) was $23.7 million for
2008 compared with $27.5 million for 2007. The effective tax rate of 37.8% for
the first half of 2008 compared with 37.5% for the same period of 2007. The
tax provision for the first six months of 2008 included the $7.7 million tax
benefit of the impairment charge, and higher tax credits from low-income
housing investments, partially offset by an increase due to the higher tax
rate for the income related to the Visa IPO. The tax provision in the same
period of 2007 reflected the tax-free nature of $822 thousand in life
insurance proceeds, higher dividend received deductions and lower
non-deductible life insurance premiums.

Classified Assets

The Company closely monitors the markets in which it conducts its lending
operations and continues its strategy to control exposure to loans with high
credit risk and to increase diversification of earning assets. Loan reviews
are performed using grading standards and criteria similar to those employed
by bank regulatory agencies. Loans receiving lesser grades fall under the
"classified" category, which includes all nonperforming and potential problem
loans, and receive an elevated level of attention to ensure collection. Other
real estate owned is recorded at the lower of cost or market value less
estimated disposition costs.

The following is a summary of classified loans and other real estate owned on
the dates indicated (dollars in thousands):

Classified loans include loans graded "substandard", "doubtful" and "loss"
using regulatory guidelines. At June 30, 2008, $33.0 million of loans or 98.4%
of total classified loans are graded "substandard". Such substandard loans
accounted for 1.4% of total gross loans at June 30, 2008. Classified loans at
June 30, 2008, increased $11.0 million from a year ago. The increase resulted
from 19 loan downgrades, partially offset by seven loan payoffs and five
upgrades. A $9.1 million increase in classified loans from December 31, 2007
was generally due to 14 downgrades, partially offset by four upgrades and four
payoffs.

One of the classified loans is a construction loan relationship with $10.3
million outstanding at June 30, 2008. The loan collateral, located north of
Sacramento, California, is comprised of land purchased for development and
construction of approximately 110 residential properties and 17 completed
residential properties. The borrower has marketed and received purchase offers
on 13 of the completed properties. Subsequent to June 30, 2008, the loan
relationship was paid down by $232 thousand with the close of escrow on one
property. The borrower also subsequently received a purchase offer on an
additional property. The number of purchase offers remains at thirteen. These
pending sales are subject to conditions typically present in similar
transactions, including potential buyers obtaining financing. The Company is
not offering financing for these pending transactions. If all of these pending
sales are successful, the Company estimates the outstanding balance on the
loan relationship will be reduced by $3.2 million. The Company recognized a
charge-off of $783 thousand during the second quarter 2008 as the anticipated
sales price of the residential units is less than the related loan balance.
Management is aggressively pursuing collection of the entire loan
relationship. The construction loan relationship was placed on non-accrual
status during the second quarter 2008 and included in non-accrual loans at
June 30, 2008.

Other real estate owned was $920 thousand, $613 thousand and $613 thousand at
June 30, 2008, December 31, 2007 and June 30, 2007, respectively. The increase
in OREO resulted from foreclosure of residential real estate loan collateral.


Nonperforming Loans and Other Real Estate Owned

Nonperforming loans include nonaccrual loans and loans 90 days past due as to
principal or interest and still accruing. Loans are placed on nonaccrual
status when they become 90 days or more delinquent, unless the loan is well
secured and in the process of collection. Interest previously accrued on loans
placed on nonaccrual status is charged against interest income. In addition,
loans secured by real estate with temporarily impaired values and commercial
loans to borrowers experiencing financial difficulties are placed on
nonaccrual status even though the borrowers continue to repay the loans as
scheduled. Such loans are classified as "performing nonaccrual" and are
included in total nonperforming assets. When the ability to fully collect
nonaccrual loan principal is in doubt, cash payments received are applied
against the principal balance of the loan until such time as full collection
of the remaining recorded balance is expected. Any subsequent interest
received is recorded as interest income on a cash basis.

Nonaccrual loans increased $6.9 million during the six months ended June 30,
2008. Twenty loans comprised the $11.7 million nonaccrual loans as of June 30,
2008. Eight of those loans were on nonaccrual status throughout the first half
2008, while twelve of the loans were placed on nonaccrual status during the
six months ended June 30, 2008. The increase in nonperforming nonaccrual loans
is primarily due to placing the construction loan relationship described in
the "Classified Assets" section on nonaccrual status. The reduction in
performing nonaccrual loans is primarily due to returning two commercial real
estate loans to accrual status based upon the payment history, payment status,
and improved financial condition of the borrowers. The Company actively
pursues full collection of nonaccrual loans.

The Company's residential real estate loan underwriting standards for first
mortgages limit the loan amount to no more than 80 percent of the appraised
value of the property serving as collateral for the loan at the time of
origination, and require verification of income of the borrower(s). The
Company had no "sub-prime" loans as of June 30, 2008, December 31, 2007 and
June 30, 2007. Of the loans 90 days past due and still accruing at June 30,
2008, none were residential real estate loans and $92 thousand were automobile
loans. Delinquent residential real estate and automobile loans on accrual
status were as follows ($ in thousands):

The Company had no restructured loans as of June 30, 2008, June 30, 2007 and
December 31, 2007.

The amount of gross interest income that would have been recorded for
nonaccrual loans for the three and six month periods ended June 30, 2008, if
all such loans had performed in accordance with their original terms, was $177
thousand and $282 thousand, respectively, compared to $109 thousand and $219
thousand, respectively, for the second quarter and the first half of 2007.

The amount of interest income that was recognized on nonaccrual loans from all
cash payments, including those related to interest owed from prior years, made
during the three and six months ended June 30, 2008, totaled $204 thousand and
$265 thousand, respectively, compared to $150 thousand and $269 thousand,
respectively, for the comparable periods in 2007. These cash payments
represent annualized yields of 7.00% and 6.16%, respectively, for the second
quarter and the first six months of 2008 compared to 12.60% and 11.38%,
respectively, for the second quarter and the first half of 2007.

No cash payments were received during the second quarter of 2008 and 2007
which were applied against the book balance of nonaccrual loans outstanding at
June 30, 2008 and 2007, respectively. No cash payments were received for the
six months ended June 30, 2008 which were applied against the book balance of
nonaccrual loans outstanding compared with $4 thousand for the corresponding
period in 2007.

Management believes the overall credit quality of the loan portfolio continues
to be stable; however, nonperforming assets could fluctuate from period to
period. The performance of any individual loan can be affected by external
factors such as collateral values, the interest rate environment, economic
conditions or factors particular to the borrower. No assurance can be given
that additional increases in nonperforming loans and other real estate owned
will not occur in the future.

Net credit losses rose in the three and six months ended June 30, 2008
compared to the three and six months ended June 30, 2007 due to lower
recoveries on commercial and automobile loans previously charged off.
Annualized net loan losses to average loans rose to 0.31% percent in
the three months ended June 30, 2008, compared to 0.24 percent in the three
months ended June 30, 2007. Management does not anticipate an increase in net
charge-off experience in the last six months of 2008 as compared to the first
six months of 2008. However, no assurance can be given that higher levels of
net charge-offs will not occur. Management continues to follow conservative
credit underwriting policies and practices, and aggressively pursues
collection of classified loans and recovery of recognized loan losses.

The Company's allowance for credit losses is maintained at a level considered
adequate to provide for losses that can be estimated based upon specific and
general conditions. These include conditions unique to individual borrowers,
as well as overall credit loss experience, the amount of past due,
nonperforming loans and classified loans, recommendations of regulatory
authorities, prevailing economic conditions and other factors. A portion of
the allowance is specifically allocated to impaired loans whose full
collectibility is uncertain. Such allocations are determined by Management
based on loan-by-loan analyses. A second allocation is based in part on
quantitative analyses of historical credit loss experience, in which
criticized and classified credit balances identified through an independent
internal credit review process are analyzed using a linear regression model to
determine standard loss rates. The results of this analysis are applied to
current criticized and classified loan balances to allocate the reserve to the
respective segments of the loan portfolio. In addition, loans with similar
characteristics not usually criticized using regulatory guidelines are
analyzed based on the historical loss rates and delinquency trends, grouped by
the number of days the payments on these loans are delinquent. Last,
allocations are made to non-criticized and classified commercial loans and
residential real estate loans based on historical loss rates, and other
statistical data. The remainder of the allowance is considered to be
unallocated. The unallocated allowance is established to provide for probable
losses that have been incurred as of the reporting date but not reflected in
the allocated allowance. It addresses additional qualitative factors
consistent with Management's analysis of the level of risks inherent in the
loan portfolio, which are related to the risks of the Company's general
lending activity. Included in the unallocated allowance is the risk of losses
that are attributable to national or local economic or industry trends which
have occurred but have not yet been recognized in past loan charge-off history
(external factors). The external factors evaluated by the Company include:
economic and business conditions, external competitive issues, and other
factors. Also included in the unallocated allowance is the risk of losses
attributable to general attributes of the Company's loan portfolio and credit
administration (internal factors). The internal factors evaluated by the
Company include: loan review system, adequacy of lending Management and staff,
loan policies and procedures, problem loan trends, concentrations of credit,
and other factors. By their nature, these risks are not readily allocable to
any specific loan category in a statistically meaningful manner and are
difficult to quantify with a specific number. Management assigns a range of
estimated risk to the qualitative risk factors described above based on
Management's judgment as to the level of risk, and assigns a quantitative risk
factor from the range of loss estimates to determine the appropriate level of
the unallocated portion of the allowance. Management considers the $54.3
million allowance for credit losses to be adequate as a reserve against losses
as of June 30, 2008.

The allocation to loan portfolio segments changed from December 31, 2007 to
June 30, 2008. The decrease in allocation to commercial loans reflects a
decrease in criticized commercial loans.

The unallocated portion of the allowance for credit losses declined $230
thousand from December 31, 2007 to June 30, 2008. The unallocated allowance is
established to provide for probable losses that have been incurred, but not
reflected in the allocated allowance. At December 31, 2007 and June 30, 2008,
Management's evaluations of the unallocated portion of the allowance for
credit losses attributed significant risk levels to developing economic and
business conditions ($4.0 million and $3.9 million, respectively), external
competitive issues ($2.0 million and $1.9 million, respectively), internal
credit administration considerations ($4.2 million and $3.2 million,
respectively), and delinquency and problem loan trends ($4.2 million and $4.1
million, respectively). The change in the amounts allocated to the above
qualitative risk factors was based upon Management's judgment, review of
trends in its loan portfolio, levels of the allowance allocated to portfolio
segments, and current economic conditions in its marketplace. Based on
Management's analysis and judgment, the amount of the unallocated portion of
the allowance for credit losses was $18.1 million at December 31, 2007,
compared to $17.9 million at June 30, 2008.


Asset/Liability and Market Risk Management

Asset/liability management involves the evaluation, monitoring and management
of interest rate risk, market risk, liquidity and funding. The fundamental
objective of the Company's management of assets and liabilities is to maximize
its economic value while maintaining adequate liquidity and a conservative
level of interest rate risk.

Interest Rate Risk

Interest rate risk is the most significant market risk affecting the Company.
Interest rate risk results from many factors. Assets and liabilities may
mature or reprice at different times. Assets and liabilities may reprice at
the same time but by different amounts. Short-term and long-term market
interest rates may change by different amounts. The remaining maturity of
various assets or liabilities may shorten or lengthen as interest rates
change. In addition, interest rates may have an impact on loan demand, credit
losses, and other sources of earnings such as account analysis fees on
commercial deposit accounts, official check fees and correspondent bank
service charges.

In adjusting the Company's asset/liability position, Management attempts to
manage interest rate risk while enhancing net interest margin and net interest
income. At times, depending on expected increases or decreases in general
interest rates, the relationship between long and short term interest rates,
market conditions and competitive factors, Management may adjust the Company's
interest rate risk position in order to manage its net interest margin and net
interest income. The Company's results of operations and net portfolio values
remain subject to changes in interest rates and to fluctuations in the
difference between long and short term interest rates.

The Company's asset and liability position remains slightly "liability
sensitive," with a greater amount of interest-bearing liabilities subject to
immediate and near-term interest rate changes relative to earning assets. As a
result, the  FOMC's recent reductions in the federal funds target rate
(charged for short-term inter-bank borrowings) and the related decline in U.S.
Treasury bill rates has improved the Company's net interest margin in the
first six months of 2008. The FOMC has not changed the federal funds target
rate since April 30, 2008 and futures markets indicate an expectation the FOMC
will not change the rate for the remainder of 2008. As a result, the Company's
net interest margin may not continue to benefit from additional reductions in
short-term interest rates. The duration of the Company's earning assets and
funding has not changed by a meaningful amount during the first six months of
2008. Management continues to monitor the interest rate environment as well as
economic conditions and other factors it deems relevant in managing the
Company's exposure to interest rate risk.


Page 29

Management assesses interest rate risk by comparing the Company's most likely
earnings plan with various earnings models using many interest rate scenarios
that differ in the direction of interest rate changes, the degree of change
over time, the speed of change and the projected shape of the yield curve. For
example, using the current composition of the Company's balance sheet and
assuming a decrease of 100 bp in the federal funds rate and a decrease of 10
bp in the 10 year Constant Maturity Treasury Bond yield during the same
period, earnings are estimated to improve 0.6% over the Company's most likely
net income plan for the twelve months ending June 30, 2009. Conversely, using
the current composition of the Company's balance sheet and assuming an
increase of 100 bp in the federal funds rate and an increase of 50 bp in the
10 year Constant Maturity Treasury Bond yield during the same period,
estimated earnings at risk would be approximately 2.9% of the Company's most
likely net income plan for the twelve months ending June 30, 2009. Simulation
estimates depend on, and will change with, the size and mix of the actual and
projected balance sheet at the time of each simulation. Management is
currently deploying tactics to reduce the "liability sensitivity" of the
Company's balance sheet to a more "neutral" condition where changes in
interest rates result in less significant changes in earnings. The Company
does not currently engage in trading activities or use derivative instruments
to control interest rate risk, even though such activities may be permitted
with the approval of the Company's Board of Directors.

Market Risk - Equity Markets

Equity price risk can affect the Company. As an example, any preferred or
common stock holdings, as permitted by banking regulations, can fluctuate in
value. Management regularly assesses the extent and duration of any declines
in market value, the causes of such declines, the likelihood of a recovery in
market value, and its intent to hold securities until a recovery in value
occurs. Declines in value of preferred or common stock holdings that are
deemed "other than temporary" could result in loss recognition in the
Company's income statement.

Fluctuations in the Company's common stock price can impact the Company's
financial results in several ways. First, the Company has regularly
repurchased and retired its common stock; the market price paid to retire the
Company's common stock can affect the level of the Company's cash flows and
shares outstanding for purposes of computing earnings per share. Second, the
Company's common stock price impacts the number of dilutive equivalent shares
used to compute diluted earnings per share. Third, fluctuations in the
Company's common stock price can motivate holders of options to purchase
Company common stock through the exercise of such options thereby increasing
the number of shares outstanding. Finally, the amount of compensation expense
associated with share based compensation fluctuates with changes in and the
volatility of the Company's common stock price.

Market Risk - Other

Other types of market risk, such as foreign currency exchange risk and
commodity price risk, are not significant in the normal course of the
Company's business activities.

Liquidity and Funding

The Company's routine operating sources of liquidity are investment
securities, consumer and other loans, deposits, and other borrowed funds.
During the first six months of 2008, investment securities provided $206.3
million in liquidity from paydowns and maturities, and loans provided $68.8
million in liquidity from scheduled payments and maturities, net of loan
fundings. The Company projects $124 million in additional liquidity from
investment security paydowns and maturities in the six months ended December
31, 2008.

At June 30, 2008, indirect automobile loans totaled $459.9 million, which were
experiencing stable monthly principal payments of approximately $19.6 million
during the last three months. During the six months ended June 30, 2008, a
portion of the liquidity provided by investment securities and loans provided
funds to meet a net reduction in deposits totaling $101.3 million. The
remaining liquidity was used to reduce higher-costing borrowed funds,
primarily federal funds purchased which declined $247.0 million. During the
first six months of 2007, investment securities provided $116.1 million in
liquidity from paydowns and maturities, and loans provided $8.8 million in
liquidity from scheduled payments and maturities, net of loan fundings. During
the six months ended June 30, 2007, a portion of the liquidity provided by
investment securities, loans and a $77.3 million increase in short term
borrowings provided funds to meet a net reduction in deposits totaling $181.7
million.

The Company held $1.4 billion in total investment securities at June 30, 2008.
Under certain deposit, borrowing and other arrangements, the Company must hold
investment securities as collateral. At June 30, 2008, such collateral
requirements totaled approximately $907 million. At June 30, 2008, $391.0
million of the Company's investment securities were classified as
"available-for-sale", and as such, could provide additional liquidity if sold,
subject to the Company's ability to meet continuing collateral requirements.

At June 30, 2008, $430.3 million in collateralized mortgage obligations
("CMOs") and mortgage backed securities ("MBSs") were held in the Company's
investment portfolios. None of the CMOs or MBSs are backed by sub-prime
mortgages. All of the CMOs and MBSs are rated AAA based on their subordination
structures without reliance on monoline insurance. Other than nominal amounts
of FHLMC/ FNMA MBSs purchased for Community Reinvestment Act investment
purposes, the Company has not purchased a CMO or MBS since November 2005. The
CMOs and MBSs have been experiencing stable principal paydowns of
approximately $10 million per month during the last three months. In addition,
at June 30, 2008, the Company had customary lines for overnight borrowings
from other financial institutions in excess of $700 million and a $35 million
line of credit, under which $374.0 million and $-0- million were outstanding,
respectively. Additionally, the Company has access to borrowing from the
Federal Reserve. The Company's short-term debt rating from Fitch Ratings is
F1. Management expects the Company can access short-term debt financing if


Page 30

desired. The Company's long-term debt rating from Fitch Ratings is A with a
stable outlook. Management is confident the Company could access additional
long-term debt financing if desired. In Management's judgment, the Company's
liquidity position is strong and asset liquidations or additional long-term
debt are considered unnecessary to meet the ongoing liquidity needs of the
Company.

The Company's profitability during the first six months of 2008 and 2007
contributed to substantial operating cash flows of $54.5 million and $47.3
million, respectively. In the first half of 2008, profitability and retained
earnings from prior years provided cash for $29.7 million of Company stock
repurchases and $20.0 million in shareholder dividends. Similarly, in 2007,
profitability and retained earnings from prior years provided cash for $20.6
million in shareholder dividends and $43.5 million utilized to repurchase
common stock.

It is anticipated that loan demand will be moderate to weak during the
remainder of 2008, although such demand will be dictated by economic and
competitive conditions. The Company aggressively solicits non-interest bearing
demand deposits and money market checking deposits, which are the least
sensitive to interest rates. The growth of deposit balances is subject to
heightened competition, the success of the Company's sales efforts, delivery
of superior customer service and market conditions. The recent series of
reductions in the federal funds rate resulted in declining short-term interest
rates, which could impact deposit volumes in the future. Depending on economic
conditions, interest rate levels, and a variety of other conditions, deposit
growth may be used to fund loans, purchase investment securities or to
reduce short-term borrowings. However, due to concerns such as uncertainty in
the general economic environment, competition, possible terrorist attacks and
political uncertainty, loan demand and levels of customer deposits are not
certain. Shareholder dividends and share repurchases are expected to continue
subject to the Board's discretion and continuing evaluation of capital levels,
earnings, asset quality, debt retirement and other factors.

Westamerica Bancorporation ("the Parent Company") is a separate entity and
apart from Westamerica Bank ("the Bank") and must provide for its own
liquidity. In addition to its operating expenses, the Parent Company is
responsible for the payment of dividends declared for its shareholders, and
interest and principal on outstanding debt. Substantially all of the Parent
Company's revenues are obtained from subsidiary service fees and dividends.
Payment of such dividends to the Parent Company by the Bank is limited under
California law. The amount that can be paid in any calendar year, without
prior approval from the state regulatory agency, cannot exceed the net profits
(as defined) for the preceding three calendar years less dividends paid. The
Company believes that such restriction will not have an impact on the Parent
Company's ability to meet its ongoing cash obligations.

Capital Resources

The Company has historically generated high levels of earnings, which provides
a means of raising capital. The Company's net income as a percentage of
average shareholders' equity ("return on equity" or ROE") has been 23.4
percent in 2006, 22.1 percent in 2007 and 19.4 percent (annualized) in the
first six months of 2008. The Company also raises capital as employees
exercise stock options, which are awarded as a part of the Company's executive
compensation programs and efforts to reinforce shareholders' interests in the
Management of the Company. Capital raised through the award and exercise of
stock options totaled $18.2 million in 2006, $14.6 million in 2007 and $20.8
million in the first six months of 2008.

The Company paid dividends totaling $40.7 million in 2006, $40.6 million in
2007, and $20.0 million in the first six months of 2008, which represent
dividends per share of $1.30, $1.36, and $0.69, respectively. The Company's
earnings have historically exceeded dividends paid to shareholders. The amount
of earnings in excess of dividends gives the Company resources to finance
growth and maintain appropriate levels of shareholders' equity. In the absence
of profitable growth opportunities, the Company has repurchased and retired
its common stock as another means to return earnings to shareholders. The
Company repurchased and retired common stock valued at $89.0 million in 2006,
$87.1 million in 2007, and $29.7 million in the first six months of 2008.

The following summarizes the ratios of capital to risk-adjusted assets for the
Company on the dates indicated:




                                                                             Well-capitalized

The Company's risk-based capital ratios increased at June 30, 2008, compared
with June 30 and December 31 of 2007, due to a decline in risk-weighted assets
and an increase in regulatory capital.

The following summarizes the ratios of capital to risk-adjusted assets for the
Bank on the dates indicated:




                                                                             Well-capitalized

The risk-based capital ratios declined at June 30, 2008, compared with June
30, 2007, due to a decrease in regulatory capital, offset in part by a decline
in risk-weighted assets. The risk-based capital ratios increased at June 30,
2008, compared with December 31, 2007, due to an increase in regulatory
capital and a decrease in risk-weighted assets.

The Company intends to maintain regulatory capital in excess of the highest
regulatory standard, referred to as "well capitalized". The Company routinely
projects its capital levels by analyzing forecasted earnings, credit quality,
securities valuations, shareholder dividends, asset volumes, share repurchase
activity, stock option exercise proceeds, and other factors. Based on current
capital projections the Company expects to maintain regulatory capital levels
exceeding the "well capitalized" standard and pay quarterly dividends to
shareholders of at least $0.35 per share. On July 24, 2008, the Board of
Directors declared a quarterly dividend of $0.35 per share, payable August 15,
2008 to shareholders of record August 4, 2008. No assurance can be given that
changes in capital management plans will not occur.


Item 3. Quantitative and Qualitative Disclosures about Market Risk

The Company does not currently engage in trading activities or use derivative
instruments to control interest rate risk, even though such activities may be
permitted with the approval of the Company's Board of Directors.

Interest rate risk and equity price risk, as discussed above, are the most
significant market risks affecting the Company. Other types of market risk,
such as foreign currency exchange risk and commodity price risk, are not
significant in the normal course of the Company's business activities.


Item 4. Controls and Procedures

The Company's principal executive officer and principal financial officer have
evaluated the effectiveness of the Company's "disclosure controls and
procedures," as such term is defined in Rule 13a-15(e) of the Securities
Exchange Act of 1934, as amended, as of June 30, 2008. Based upon their
evaluation, the principal executive officer and principal financial officer
concluded that the Company's disclosure controls and procedures are effective.


Page 32

The evaluation did not identify any change in the Company's internal control
over financial reporting that occurred during the quarter ended June 30, 2008
that has materially affected, or is reasonably likely to materially affect,
the Company's internal control over financial reporting.


PART II. OTHER INFORMATION


Item 1. Legal Proceedings

Due to the nature of the banking business, the Bank is at
times party to various legal actions; all such actions are of a
routine nature and arise in the normal course of business of the
Subsidiary Bank.


Item 1A. Risk Factors

In March 2008, the Bush administration outlined a sweeping plan to streamline
financial regulation in the United States. The proposals would consolidate
regulatory agencies and revamp oversight of the financial system. Some of the
proposals would shift regulatory power from states to the federal government.
The proposals would require passage of Congressional legislation. The impact
of these proposals on the future regulation of the Company is uncertain at
this time.

The Federal Deposit Insurance Corporation ("FDIC") insures deposits at FDIC
insured financial institutions up to certain limits. The FDIC charges insured
financial institutions premiums to maintain the Deposits Insurance Fund.
Current economic conditions have increased expectations for bank failures, in
which case the FDIC would take control of failed banks and ensure payment of
deposits up to insured limits using the resources of the Deposit Insurance
Fund. In such case, the FDIC may increase premium assessments to maintain
adequate funding of the Deposit Insurance Fund. An increase in premium
assessments would increase the Company's expenses.

There are no other material changes to the risk factors disclosed in the
Company's Annual Report on Form 10-K for the fiscal year ended December 31,
2007.

The Company repurchases shares of its common stock in the open market to
optimize the Company's use of equity capital and enhance shareholder value and
with the intention of lessening the dilutive impact of issuing new shares to
meet stock performance, option plans, and other ongoing requirements.

Shares were repurchased during the first quarter of 2008 pursuant to a program
approved by the Board of Directors on August 23, 2007 authorizing the purchase
of up to 2,000,000 shares of the Company's common stock from time to time
prior to September 1, 2008.


Item 3. Defaults upon Senior Securities

      None


Item 4. Submission of Matters to a Vote of Security Holders

Proxies for the Annual Meeting of shareholders held on April 24,
2008, were solicited pursuant Regulation 14A of the Securities
Exchange Act of 1934. The Report of Inspector of election
indicates that 24,954,515 shares of the Common Stock of the
Company, out of 28,890,389 shares outstanding on the February 25,
2008 record date, were present, in person or by proxy, at the
meeting. There were no "broker non-votes" because the election of
directors is considered "routine" under applicable exchange rules
and therefore, on this matter, brokers were able to vote shares
for which no direction was provided by the beneficial owner. The
following matter was submitted to a vote of the shareholders:

1. - Election of directors:
